It’s an open question whether the tailor convicted of his murder was actually one of them. Whelan, like McGee, was an Irish immigrant and supposedly a Fenian sympathizer. He also matched the gunman’s description.

Whelan was snatched up within 24 hours and convicted on essentially circumstantial evidence.

Hanged in a snowstorm before thousands, he maintained his innocence to the end — a plea that has had its advocates in posterity, including a high-profile recent play. Whelan bolsters his own case by haunting the jail where he met his fate … a structure which still stands today, now serving as a (singularly atmospheric) hostel.
